Ah, good, thanks.

I'm not completely surprised, because I remember when writing
`font-lock-ensure` that there are many corner cases some of which seem
very difficult to fix without actually enabling `font-lock-mode`, but we
should still strive to be "as close as possible", so ... do you have
a bug report with some concrete cases we could try to fix?
